SPECIFICATION forming part of Letters Patent No. 609,670, dated August 23, 1898.

Application filed February 7, 1898. erial No. 669,411. (No model.)

To aZZ whom it may concern..-

Beit known that LSAMUEL ALFRED HAINES, a citizen of the United States, and a resident of Garrett, in the county of Ellis and State of Texas, have invented certain new and useful Improvements in Wrenches; and I do hereby declare that the followingis a full, clear, and

exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification.

My invention relates to wrenches for removing the nuts from vehicle-axles; and its object is to provide an improved construction of the same having means for engaging with.

the rim of a Wheel-hub whereby the nut is. removed or screwed on by turning the Wheel.

My invention consists, essentially, in the combination, with an ordinary wrench, of an adjustable head having a slot which engages with the shank of the wrench and formed with a socket adapted to engage with the rim of the wheel-hub and provided with a setscrew for holding it in place, as hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is an elevation of an ordinary wrench provided with my improvements. Fig. 2 is a vertical cross-section of the same. Fig. 3 is a perspective view of the head which engages with the wheel-hub rim removed.

In the said drawings, the reference-numeral 1 designates a wrench for removing the nuts from vehicle-handles which may be of any ordinary or suitable construction.

The numeral 2 designates my improved attachment or head, consisting of a metal block formed with a rectangular opening 3 and an intersecting slot 4 at one end, with which openingis adapted to engage the shank of the wrench. At the opposite end said head is formed with two outwardly-extending arms 5 and 6, one of which is formed with a screwthreaded opening for the passage of a setscrew 7.

The numeral 8 designates a short screwthreaded bolt having a head 9 and a nut 10. This bolt is inserted in the slot 4, with its head resting against the shank of the wrench, and the nut 10 is then screwed on the outer end thereof, thereby securely holding the head to the shank.

In practice one edge of the wrench-shank is passed through the slot 4 at the end or head of the block 2 and is then turned so that the flat sides of the shank will engage with the upper and lower walls of the opening 3. To remove the nut, the rectangular jaw of the wrench is engaged with the nut and the arms 5 and 6 engaged with the rim of the wheelhub and held securely thereto by the setscrew 7. By now turning the wheel backward the nut will be unscrewed. A reverse movement will screw the nut home. By this means a greatleverage is obtained, so that the nuts may be readily screwed up and unscrewed. The head. or block 2 is adjustable on the shank, which loosely passes there through, so that it can be moved to and from the jaw, so as to adapt the device to hubs of varying sizes.

For the purpose of preventing injury to the wheel-hub by the set-screw 7 I provide the block with a recess 8', in which is seated one end of a spring-plate 9'. The set-screw in this instance does not come in contact with the wheel-hub, but presses the plate against the same. By this means while the head is securely held to the hub marring or otherwise injuring the latter is prevented.

, In some cases I may make the head or block integral with the shank of the wrench; but I prefer the construction first described, as the head can be adjusted to suit varying sizes of hubs.

Having thus fullydescribed my invention, what I claim is- 1. As an improved article, an attachment for wrenches consisting of the head formed with an opening in one end and an intersecting slot, the arms at the opposite end and the set-screw, substantially as described.

2. The combination with a wrench, of the head formed with an opening and an intersecting slot at one end and the headed bolt engaging with said slot, its nut, the arms at the opposite end of said head, the set-screw passing through one of said arms, and the spring-plate located between said arms, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

SAMUEL ALFRED HAINES.
